In this case, if i put the formula `NOW()` in `F2`, whenever it changes, the image will also be updated in cache? Did you know telling me?

> Images are cached aggressively. You can work around this by causing your URL to update when data changes: [image] Here I’ve made a URL that changes every time the value in F2 changes. I’ve added a fake URL parameter, cachebust (the name does not matter), at the end of the URL. This is totally ignored, but it makes the URL look brand new when the data changes.
